1. 以PrintWriter来实现写入

import java.io.*;

public class test {

/**
* @param args
*/
public static void main(String[] args) {
String path="e://a.txt";
try {
FileWriter fw=new FileWriter(path,true);
PrintWriter pw=new PrintWriter(fw);
pw.println("世界");
pw.close();
//bw.close();
fw.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

2. 以BufferedWriter来实现写入
[php]
import java.io.*;

public class test {
    /** * @param args */
   public static void main(String[] args) {
           String path="e://a.txt";
           try {
                FileWriter fw=new FileWriter(path,true);
                BufferedWriter bw=new BufferedWriter(fw);
                bw.newLine();
 bw.write("Hello");
 bw.newLine();
 bw.write("世界");
 bw.close();
  fw.close();
         } catch (IOException e) {
              // TODO Auto-generated catch block
             e.printStackTrace();
          }
  }
